I use Python REPL for simpler arithmetic operations
The perldl shell, which is part of PDL, can be handy for the same thing:
C:\>perldl
perlDL shell v1.357
PDL comes with ABSOLUTELY NO WARRANTY. For details, see the file
'COPYING' in the PDL distribution. This is free software and you
are welcome to redistribute it under certain conditions, see
the same file for details.
ReadLines, NiceSlice, MultiLines enabled
Reading PDL/default.pdl...
Found docs database C:/_64/strawberry-5.26.1-PDL/perl/vendor/lib/PDL/p
+dldoc.db
Type 'help' for online help
Type 'demo' for online demos
Loaded PDL v2.018 (supports bad values)
Note: AutoLoader not enabled ('use PDL::AutoLoader' recommended)
pdl> p sqrt(9**5)
243
pdl>
And no need to explicitly import anything !
Cheers, Rob

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
